to the web service
using ksoap
but i am getting the NPE
. In the code "exit_distance" is double value. can any body find the error in that and send the sample example
code here
//valus required for test
RB_Constant.RB_Webservice_URL = ?
RB_Constant.RB_Webservice_Namespace = ?
public String getExitsRestaurants() throws SoapFault
{
String data = "";
String serviceUrl = RB_Constant.RB_Webservice_URL;
String serviceNamespace = RB_Constant.RB_Webservice_Namespace;
String soapAction = "http://www.roadbrake.com/GetExitDetailsExtn";
String type_of_soap = "GetExitDetailsExtn";
try
{
SoapObject Request = new SoapObject(serviceNamespace, type_of_soap);
PropertyInfo HighwayIdObj = new PropertyInfo ();
HighwayIdObj.name = "HighwayId";
HighwayIdObj.type = PropertyInfo.INTEGER_CLASS;
Request.addProperty("ExitNo", 7);
Request.addProperty(HighwayIdObj, highwayid);
Request.addProperty("HighwayName", 95);
Request.addProperty("exit_distance", 1.2);
System.out.println("Request Value->"+Request.toString());
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
MarshalDouble md = new MarshalDouble();
md.register(envelope);
envelope.setOutputSoapObject(Request);
try
{
HttpTransportSE androidHttpTransport = new HttpTransportSE(serviceUrl);
androidHttpTransport.call(soapAction, envelope);
}
catch(Exception e)
{
System.out.println("Webservice calling error ->"+e.toString());
}
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
data = response.toString();
System.out.println("web service response->"+response.toString());
}
catch(Exception e)
{
System.out.println("Soap Method Error ->"+e.toString());
}
return data;
